In short, pragmas are all-same-case "use" names; instead of loading code, they tell the compiler to change its behavior.
The MONKEY-* pragmas generally control various kinds of unsafe or dangerous behavior, including direct access to the mechanisms underneath / "supporting" Rakudo and things like EVAL. Other all-uppercase names also generally represent "dangerous" actions or options. There are a few pragmas that are all lowercase instead of all uppercase; they also change the compiler's behavior, but are safer than the all-uppercase ones. "use lib" is one of them. (This is why modules are generally mixed-case names.) https://docs.perl6.org/language/pragmas for more information.
